-    #
-    # Verified against https://codecompanion.olimorris.dev/configuration/adapters-acp
-    # (CodeCompanion >= v18.0.0, which is what's pinned by nixvim's nixpkgs as of
-    # 2026-08). Two things changed from an older/assumed layout:
-    #   - the default-adapter key is `interactions.chat.adapter`, not
-    #     `strategies.chat.adapter` (renamed in v18.0.0);
-    #   - the built-in adapter names are `claude_code` and `gemini_cli` (no
-    #     `_acp` suffix) and live under `adapters.acp.<name>`.
-    #
-    # Neither adapter has a true zero-config mode that silently piggybacks on
-    # an already-logged-in CLI session:
-    #   - gemini_cli: `defaults.auth_method = "oauth-personal"` reuses the
-    #     `gemini` CLI's own login — no key needed, closest thing to "just
-    #     use my existing session".
-    #   - claude_code: there's no oauth-personal equivalent. Run
-    #     `claude setup-token` once (ties to your Pro/Max subscription rather
-    #     than a Console API key) and save the result to
-    #     ~/.config/codecompanion/claude-oauth-token (chmod 600, outside the
